Description: CPU INFOrmation library (binary utilities)
cpuinfo is a library to detect essential for performance optimization
information about host CPU.
Features
- **Cross-platform** availability:
- Linux, Windows, macOS, Android, and iOS operating systems
- x86, x86-64, ARM, and ARM64 architectures
- Modern **C/C++ interface**
- Thread-safe
- No memory allocation after initialization
- No exceptions thrown
- Detection of **supported instruction sets**, up to AVX512 (x86) and
ARMv8.3 extensions
- Detection of SoC and core information:
- **Processor (SoC) name**
- Integrated **GPU name** (Android/iOS only)
- Vendor, **microarchitecture**, and ID (**MIDR** on ARM, **CPUID**
leaf 1 EAX value on x86) for each CPU core
- Detection of **cache information**:
- Cache type (instruction/data/unified), size and line size
- Cache associativity
- Cores and logical processors (hyper-threads) sharing the cache
- Detection of **topology information** (relative between logical
processors, cores, and processor packages)
- Well-tested **production-quality** code:
- 60+ mock tests based on data from real devices
- Includes work-arounds for common bugs in hardware and OS kernels
- Supports systems with heterogenous cores, such as **big.LITTLE**
and Max.Med.Min
- Permissive **open-source** license (Simplified BSD)
This package ships with several binary utilities.
